PERSISTENT CURRENT IN FISHBONE-TYPE DNA RING

We investigated the behavior of the persistent current in the DNA ring in a Fishbone structure threaded by a magnetic flux , varying the electron number Ne, and the sequence size N. To this end, we use a tight-binding Hamiltonian and the Schrodinger equation. Our results show that the amplitude of the persistent current triangular oscillations increase with increasing Ne and decrease with increasing N. These factors were crucial in defining the profile of the persistent current in the DNA ring. Aspects of the saw-tooth oscillations were analyzed as a function of , revealing a range of possibilities in applications in nanotechnology.
